The Kardashian clan keeps the rumor mill churning: Is Khloe really a Kardashian? Did matriarch Kris Jenner have cosmetic surgery? And what about Kanye and Kim, aka "Kimye?" TODAY's Matt Lauer grilled Jenner Tuesday on each and every one of these important slivers of gossip.

"Ridiculous!" said Jenner to both whether she's about to get fired as "mom-ager" to her daughters and to whether Khloe's real dad is Robert Kardashian. "The girls sell magazines ... it's easy fodder. So the girls and I work together every single day, and we have an amazing relationship and ... I know when to take that (mom-ager) hat off and when to put it on. We have a nice relationship."

As for that fat lip Jenner sports in an upcoming episode of "Keeping Up with the Kardashians," which is now in the midst of filming its seventh season, there was no cosmetic surgery, but Jenner remained coy as to the reason behind it. "You have to tune in, because it's unbelievable," she said.

Yes, yes, but ... Kanye! What about Kim's relationship with Kanye? That's where Jenner buttoned her lip. "I stopped commenting about the details in my kids' friendships and relationships, because I get nothing but in trouble," she said, then added, "He's great and she seems happy."

With all of these rumors and misinformation that gets out there, though, Lauer had to wonder: Why keep doing the show? Jenner recently signed on for three more seasons, and he asked about losing private time. "It's almost unusual not to have all the cameras in our lives," she said. "It's an opportunity for me as a mom -- I get to wake up every single day and work with my kids.... It's somewhat addictive in that ... we can't wait to do it."
